- Referring particularly to Figs. 1 to 7, wherein the preferred form of the invention is shown as applied to the form of swing reed shown in U. S. Patent to Holmes No. 1,926,382, the loom frame l supports a top shaft II which by means of connectors [2 cause back and forth reciprocation of the lay l3 as the shaft rotates. The connectors drive the lay by means of pins l4 each of which passes through a pair of ears I projecting rearwardly from the lay. A hand wheel is on shaft ll aifords means for manually moving the lay backwardly and forwardly. The lay has an upwardly extending born I! at each end thereof on which a bearing l8 is'vertically adjustable relatively to the lay.

'A hand rail l9 extending across the loom has bolted to each end thereof a carrier 20 provided with a stud 2| rockable in the corresponding bearing I8. The reed 22- has its top rail 23 clamped against angle section 24 secured to the hand rail and has its bottom rail 25 normally held forwardly against partof the lay by a backstay' 26 extending'across the lay. l

- Engaging each endof the backstay is a resilient positioner, designated generally at 21, pivoted on a stud 28 fixed to the lay. A'spring 29 for each positioner the force'of which is adjustable as at 30 tends normally to hold the bottom rail 25 in forward position relatively to the lay, but yields to permit pivotal rearward movement of the bottom of the reed by the fell of the cloth when the lay moves to front center. Each end of the backstay is connected to'the corresponding end of angle section 24 by a tie member 3|.

Reed elements similar to that already described are generally known as swing reeds. For an understanding of further details of the lay and reed reference may be had to the previously mentioned Holmes patent.

Looms ordinarily have cloth take-up mecha nisms one example of which is shown in Fig. 1. The cloth C is wrapped around a take-up roll 35 turned by means of a train of gears including a ratchet wheel 36 which is advanced in a counterclockwise direction as viewed in Fig. 1 during loom operation. A feed pawl 31 and hold pawl 38 'are'of usual construction and can be lifted to permit manual reverse movement of the ratch- 4 et wheel, or yield when the ratchet wheel is advanced manually. Further description of the take-up is not thought necessary, and it will suffice for present purposes to state that when the ratchet wheel is advanced manually of the cloth fell F is moved forwardly.

The matter thus far described is of common construction and is given herein as examples of swing reeds and take-ups usable with the present invention.

As already stated the fell of the cloth is likely to move rearwardly during a period of loom stoppage with the result that upon resumption of weaving a thick place or starting mark will be formed in the cloth. It is the general purpose of this invention to provide a gauge having indicators which can be aligned by manipulation of the take-up when weaving is resumed to avoid the aforesaid starting marks.

In carrying the preferred form of the invention into effect the loom is provided with gauges GR and GL located, respectively, at the right and left sides as indicated in Fig. 7. Since both 01. these gauges are alike only one of them will be described in detail. Gauge GL comprises a scale 40 havin a primary indicator or graduation 4| which is parallel to the length of the lay. The scale is secured to an ear l5 and faces upwardly and may be a thin fiat strip or the like fastened in any approved manner to the top of the ear. If the scale is in the form of flexible paper, metal foil, or a decalcomania it will adhere directly to the ear, but if the scale is in the form of a sheet metal plate, not shown, it can be held to the ear in appropriate manner.

Secured to the adjacent tie member 3! is a secondary indicator shown here in the form of an indexing pointer 42 having an elongated body 43 in which are formed vertically spaced vertical slots 44, see Fig. 2. A holding screw 45 passes through upper slot 44 and is tapped into the tie member 3| to hold the indexing pointer in fixed position with respect to the reed. Extending laterally from the body 43 is a pointing or indicator finger 46 which overhangs the scale 40.

In order to afford some means for adjusting the back and forth position of the pointing finger with respect to the member 3| an adjusting screw 41 is tapped into the member and formed with a reduced right end 48, see Fig. 3, passing through the lower slot 44. The indexing pointer may be made of flat spring metal and is held by its resilience against screw 41. Turning of the adjusting screw means 41 effects adjustment of the pointer finger 46 backwardly and forwardly relatively to the reed.

I operation, the loom will be run long enough to establish correct location of the fell, after which the loom will be stopped and the lay moved to its front center position. The fell of the cloth will cause relative rearward movement of the lower part of the reed with respect to the lay and will also cause movement of the indicator finger 46 with respect to the scale 4!]. Screw 41 is then manipulated until the pointing finger is directly over or vertically registered with the indicator or graduation 4|. Thisalignment can be effected by looking down from a position above the hand rail. The finger 46 should be as close as possible to the scale 40 without touching the latter in order that the error of registering the indicators may be reduced to a minimum. The two indicators will then be correctly set with respect to each other, and weaving can be resumed.

When the loom is to be started up after a lither ha be a rea w d mevemei t' oi t ell of th cl t d i nsth r fr e if totnass the reed will be pushed rearwardly' beyond j cprre ct position and the indicators will notreg 'r,'"" n'd the indicator on the .lay' occupying some such rearward position as indicated in F i815. The weaver then manipulates fil take-up mechanism, as ,by movement or the ratchet wheel mer t Cldth e l 'a d r ntil e idle or inoves forwardly'into m e a F with" the graduation or indicator- Q1, 'or'to h 0s, ion shown Fig. 6; ,The relation of the l t w; respect to the lay will then bethe'sarrie t a which existe at t e en or the g mes, or 160m operation; aniline lporn can be ,7 e p without producing a starting mark.

When the two parts, members," of'indicators of the gauge are given their initial setting as 'tl eed des ribed, 'el be e t y will ordiii'arilfretain this setting so that it will not be necessary to alter the position of the reed carried'indicator from day today. If, for any reaconditions in the'loorn should cause a slight change in the'beatf-up "conditions a compensating adiust'mentof screw E1 will return the parts of the gauge into registry. Experience has shown that persons possessed of little' or no skill in \yeev,ins; are able by effecting registerot the indicators as descrihed'to'st'art up a loom without oroducing a starting niarkin the cloth.

" The continued use of the reed may; eventually wear slight depressions in theli orward edges of the reeddehts, iii which event it will be desirehle'to change the vertical position of the reed. Itis for this reason that the hearings it! are made top it vertical adjustment. If the reed should be ed upwardly withrespect to the lay to firesent a new part of the reed dents to the fell of the cloth, the pointing: finger or indicator 45 can be lowered mummy to the reed hy means of screw, 45 so that it will be. close to the graduatio or indicator 4| Likewise, the reed should b" wered the pointing finger will be adjusted;

Reterring particularly to Figs.v 9 and; 10; the lay 58; is provided with a ley end 5! on which is mounted a bearing 52. The latter is held to the: lay end by upper and lower bolts 53 and respectively, which pass through horizontal slots; 55 in the; bearing and through the lay end and are provided at their rear ends; with nuts: 55 The bearing member 52-; has a bearing hub 51 which receives a guclgeon or trunnion 53 on plate or'reed hanger; 5,9.

The top of the gauge member 15 is bent generally' horizontally and laterally to the left, see Fig. 9, to form a wing 86 which may if desired be inclined slightly downwardly and forwardly. Extending across the top of this wing and preferably parallel to the lay is a graduation, indicator or mark 8i which corresponds to the pointing finger or indicator 46 already described.

The other gauge member 16 is provided with a vertical body 82 having a downwardly opening slot '83 in a foot 84 at the lower end thereof through which the top bolt 53 passes. The upper part of the gauge member 16 has a wing 35 bent forwardly, see Fig. 9, and preferably inclined similarly to wing 38. Wing 85 is provided with a graduation, indicator or mark 86 which may be parallel to the lay and similar to indicator 8|. Indicators 83 and 8| may be considered as primary and secondary indicators, and can conveniently be struck into their respective wings as linear grooves.

The gauge member 15 is adjustable angularly with respect to plate 59 in a back and forth direction, or in a direction parallel to the plane at which the reed swings. Gauge member 16, which is held under the head of bolt 53, can be adjusted in a right and left hand direction as viewed in Fig. 9 to move its wing 85 toward or from wing 80. Gauge member 16 is also vertically adjustable on the lay to enable both wings B and 85 to be at the same level by proper manipulation of the bolt 53. The two wings can therefore be placed in close proximity to each other without actual engagement.

The settings of the two gauge parts 75 and 16 of the first modified form of the invention will be similar to those already described for the preferred form of the invention. The graduations or indicators 81 and 86 will be caused to align when the lay is on front center after normal weaving conditions have been established. This alignment can be made by angular adjustment of the gauge part 15 and manipulation of screw 62, and after this adjustment is once made it will ordinarily not be necessary to change it.

After a period of loom stoppage the lay will be moved to its front center position and if there has been rearward movement of the fell of the cloth the graduation 8| will be slightly in advance of graduation 86. The take-up can then be manipulated until the fell of the cloth advances to a point where the two graduations or indicators 8! and 86 will be in lineal alignment, after which weaving can be resumed with assurance that no starting mark will be produced in the cloth.

As shown in Fig. 12 the type of gauge shown in Fig. 9 can be applied to each end of the lay or reed for the purposes already described in connection with the preferred form of the invention. In Fig. 12 it should also be noted that lineal alignment of the indicators or marker lines 8! and 86 will be visible throughout quite a wide visual angle. If the weaver is at the left end of the loom the alignment can be determined from any point in the angle such as that designated at a, and if at the right hand end of the loom the alignment can be seen throughout angle 2). If the weaver is in front of the loom the alignment of the graduations or indicators 8! and 86 can be determined from almost any position in space 0 which the weaver will normally occupy. It will thus be seen that 8 the gauge shown in the first modification of the invention does not require a vertical line of vision as is the case in the preferred form of the invention.

The second modification may be used in con nection with the same form of swing reed suspension set forth in Figs. 9 to 11, but instead of having upwardly extending gauge members as in the first modification the gauge members ex tend downwardly, and furthermore, the gauge members are identical.

Referring to Fig. 15, the two gauge members used in the second modification of the invention are designated at and 9!. These members are identical and may be made of sheet metal bent to form a vertical wall or foot 92 and a horizontal shelf or wing 93. Wall 92 has a slot 94 to fit either of the fastening means constituted by the bolt 54 Or screw 63. The wing 93 has a primary indicator parallel to wall 92 and a secondary indicator as at right angles to wall 92 and indicator 95. These indicators can be made in a stamping operation and be in the form of grooves.

When member 96 is held in place by bolt 54 with its wall parallel to the lay its primary indicator will be parallel to the lay, and when member 91 is held in place by screw 63 with its wall perpendicular or at right angles to the lay its secondary indicator will be parallel to the lay. The secondary and primary marks of members as and 9 I, respectively, will not be used. The slot 94 is such as to permit adjustments of each wing 93 relatively to the other and with respect to the support therefor.

It is believed that the operation of this second form of gauge will be understood without extended description. It operates in a manner very. similar to the first modified form of the inven tion except that the aligned indicators are below the pivot of the swing reed. Since both members 90 and 9! are identical only a single type of indicator member need be made.

When the second modification of the invention is employed it can be located in a partly inclosed protected space or pocket It! between plate 59 and a usual shuttle box mouth member or shuttle guard H32 which is secured as at I03 to a part of the bearing member 52. When thus located; the indicator members 95 and M will not project; beyond the space or pocket Ifll, and will be pro-- tected against accidental derangement.

From the foregoing it will be seen that the invention sets forth simple means by which the.- weaver may correctly locate the position of the: swing reed with respect to the lay after a period of loom stoppage with assurance that when weaving is resumed there will be no starting mark.

in the cloth. Each form of the invention com-- prises essentially two indicators one of which may be considered a primary indicator on the lay and the other of which is a secondary indicator'which becomes aligned with the primary indicator as the fell of the cloth due to manipulation of the take-up permits the swing reed to move forwardly relatively to the lay when the latter is on front center position. In the preferred form of the invention one of the indicators is over the other, but in the other twoforms of the invention the indicators move into lineal alignment when registering. The inven tion is not necessarily limited to the forms of in dicators shown herein and it will be sufficient if the lay and reed are each provided with. a device which serves as a graduation, indicator, mark or. thetlike, In, thegsecondandthlrd forms of; the invention. the. lineal. alignment canibe seen from quitea wideivisual. angle. and can be de.-- tected. by. the weaver. from a. position which, is

convenient. fon turning the. take-upv ratchet 51 wheel. Inallforms of theinvention the fact that. there. is a-gaugeateachend of. the reed permits. an adjustment of the. springs so that they amount by Whichthey. yieldlwhenuthe lay moves to. front center can be equalized. In the secondlmodifie 1'0: cation the indicator members are identical and canflconveniently be located. ina protected space or pocket which is: foundin. the construction of certain typesoflays providedwith. swing. reeds.
